IMPROVEMENT IN UTLETS FOR SINKS, &c.

Specificationformin g part of Letters Patent No. 149,489, dated April 7,1874; application filed March 6, 1874.

To all whom it may concern:

Be it known that I, JASON LEWIS, of Providence, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in the Outlet of Sinks, 8vo., of which the following is aspeciiication, referring to the accompanying drawing making part of thesame, in which- Figurel is a vertical section of a trap-outlet of a sinkwith my said improvement. Fig. 2 is a plan or top view of the same, withpart ot' the strainer broken away to give an unobstructed view of theparts beneath it. Figs.

` 3 and 4 are details of the application of my improvement to the nozzleH, hereinafter fully explained. Figs. 5 and 6 are details of the screwand cross-bar, also herein fully explained.

Similar letters mark like parts in all the JrigllleS.

My invention relates to the means for fastcnlng the strainer over theoutlet of the sink in a simple, cheap, and effective manner; and

consists orn a screw passing through the center of the strainer, andscrewing into the middle of a removable crossbar extending across theoutlet, the object being to secure the strainer in its place, so that itmay be readily removed for clearing the trap and outlet of anyobstructions, but in a manner that requires no drilling or tapping ofholes into the cast-iron sink or outlet, so that all diftcult handlingof the heavy sink for such purpose is avoided, and that requires nochange in the construction of the parts, except two slight notches inthe outlet, whereby `all difficulty of casting and imperfection of thesame are entirely avoided.

In the drawing, H is the outlet, and A is the surrounding basin, of acast-iron sink, forming part of the cast-iron bottom ofthe same. S isthe strainer, having a dome above, and a lange, F, beneath, extendingbelow the upper edge c of the nozzle or out-let H,

4into the said basin A, to form a stench-trap,

in a manner well known, besides stiftening the strainer to resist blowsand pressure upon it.

In order that the strainer shall exclude ob structions and the trapoffensive smells, it must be secured in its place over the outlet. Thishas been done in anumber of ways heretofore, but none of which, so faras I am aware, without some kind of objection, most of which by thisinvention of mine I have been able to overcome or avoid altogether. Thisis accomplished by providing a cross-bar, D, across the outlet H, whichis made separately from the sink casting, and preferably ot' brass orincorrodible metal, and is held by its ends in two dovetail notches, I,inthe lower edge of the outlet H, as shown in Figs. l and 4f.4 Thesenotches are rst east in the form shown in Fig. 3, so as to readily drawfrom the mold, and are afterward filed into the dovetail form, and afterthe cross-bar D is in serted thereinit may be permanently secured in itsplace by spreading the ends of the crossbar by hammering it. In themiddle of the crossbar a hole is drilled and tapped, into which thesingle screw T, which passes through. the center of the strainer,`isscrewed, the head of the screw bein g eountersunk in the strainer, andby sett-ing up the screw the strainer is secured in its place.

This device is extremely simple, but its utility will be fullyunderstood and appreciated when it is considered that it is almostimpossible to cast a cross-bar likel D across the nozzle, owing to itsliability to come iniperfect, and thus spoil the whole sink; and evenit' these could be cast perfect, the whole sink would have to be liftedand handled and properly mounted to drill and tap the hole in thecross-bar for the screw T, which in the separate crosslbar is entirelyavoided, and the work is greatly simpliiied and cheapened with outnecessity of changing the construction of the sinks pattern, except inthe matter of the notches, whereby it is readily applied to any sinknozzle or outlet.

The waste-pipe is secured upon the outside of the nozzle H to lugsprovided for the purpose, or in any well-known and effective man ner.

Having described my invention, I claim- The screw T and cross-bar D, incombination with the strainer and outlet of the sink, as described, whenarranged and applied thereto substantially in the manner and to eiiectthe purpose specified.

JASON LEWIS.
